Remove bootstrap VM and some other assets

[e-minguez]

Fixes #52 #71

[e-minguez]

I'm not sure if:

• Removing the virtual networks is useful
• Removing the ocp/ folder is useful
• Removing the 172.22.0.2 from the ~/.ssh/known_hosts is useful

Comments?

I am of the opinion that removing hte virtual network is not useful
Think the other two make sense

Did you look to see what @hardys recommended - using openshift_baremetal_intaller destroy cluster?

[e-minguez]

IIRC @hardys mentioned here is there is no complete support right now for destroy cluster.

I've just executed it and:

$ ocp/openshift-baremetal-install destroy cluster --log-level debug --dir ocp/
DEBUG OpenShift Installer v4.2.0                   
DEBUG Built from commit 8c9abe40f7616303c03cafdc9ad612cd8fa7bd6b

@e-minguez Just would like to confirm you tested

[e-minguez]

Can confirm I tested it. The Masters are not cleaned but that's because the destroy cluster command doesn't do it. I think this is the most clean stuff we can make right now.
